Fatalities Associated with Nonconvective High-Wind Events in the United States
(American Meteorological Society, 2008)A database was compiled for the period 1980?2005 to assess the threat to life in the conterminous United States from nonconvective high-wind events. This study reveals the number of fatalities from these wind storms, their ... -
Effects of Future Climate and Biogenic Emissions Changes on Surface Ozone over the United States and China
(American Meteorological Society, 2008)Future projections of near-surface ozone concentrations depend on the climate/emissions scenario used to drive future simulations, the direct effects of the changing climate on the atmosphere, and the indirect effects of ... -
Dynamic LES Modeling of a Diurnal Cycle
(American Meteorological Society, 2008)The diurnally varying atmospheric boundary layer observed during the Wangara (Australia) case study is simulated using the recently proposed locally averaged scale-dependent dynamic subgrid-scale (SGS) model. This tuning-free ... -
A Geographic Information Systems–Based Analysis of Supercells across Oklahoma from 1994 to 2003
(American Meteorological Society, 2008)Oklahoma is a region that is well known for its high frequency of severe thunderstorms, which vary in activity, mode, and coverage. In particular, this region experiences a significant number of highly organized supercell ... -
Downslope Flows on a Low-Angle Slope and Their Interactions with Valley Inversions. Part II: Numerical Modeling
(American Meteorological Society, 2008)The characteristics of well-developed downslope winds observed by tethered balloon soundings at multiple locations over a low-angle slope in the Salt Lake Valley are studied using the Regional Atmospheric Modeling System ... -
Downslope Flows on a Low-Angle Slope and Their Interactions with Valley Inversions. Part I: Observations
(American Meteorological Society, 2008)Thermally driven downslope flows were investigated on a low-angle (1.6°) slope on the west side of the floor of Utah?s Salt Lake Valley below the Oquirrh Mountains using data from a line of four tethered balloons running ... -
Potential Benefits of Seasonal Inflow Prediction Uncertainty for Reservoir Release Decisions
(American Meteorological Society, 2008)This paper examines the conditions for which beneficial use of forecast uncertainty may be made for improved reservoir release decisions. It highlights the parametric dependencies of the effects of uncertainty in seasonal ... -
Biogeography of Tropical Montane Cloud Forests. Part I: Remote Sensing of Cloud-Base Heights
(American Meteorological Society, 2008)Cloud-base heights over tropical montane cloud forests are determined using Moderate Resolution Imaging Spectroradiometer (MODIS) cloud products and National Centers for Environmental Prediction global tropospheric final ... -
Interaction between Coastal Upwelling and Local Winds at Cabo Frio, Brazil: An Observational Study
(American Meteorological Society, 2008)The relationships between coastal upwelling and local winds at Cabo Frio (Brazil) are studied using SST and time series of surface wind for a 10-yr period (1971?80). The results show that the seasonal variations of SST and ... -
A Binned Approach to Cloud-Droplet Riming Implemented in a Bulk Microphysics Model
(American Meteorological Society, 2008)This paper presents the development and application of a binned approach to cloud-droplet riming within a bulk microphysics model. This approach provides a more realistic representation of collision?coalescence that occurs ... -
Momentum Transfer within Canopies
(American Meteorological Society, 2008)To understand the basic characteristics of the observed S-shaped wind profile and the exponential flux profile within forest canopies, three hypotheses are postulated. The relationship between these fundamental profiles ... -
An Exploratory Study to Derive Precipitation over Land from X-Band Synthetic Aperture Radar Measurements
(American Meteorological Society, 2008)Global precipitation measurements from space-based radars and microwave radiometers have been the subject of numerous studies during the past decade. Rainfall retrievals over land from spaceborne microwave radiometers ... -
Validation of Cloud Liquid Water Path Retrievals from SEVIRI Using One Year of CloudNET Observations
(American Meteorological Society, 2008)The accuracy and precision are determined of cloud liquid water path (LWP) retrievals from the Spinning Enhanced Visible and Infrared Imager (SEVIRI) on board Meteosat-8 using 1 yr of LWP retrievals from microwave radiometer ... -
Estimation and Extrapolation of Climate Normals and Climatic Trends
(American Meteorological Society, 2007)WMO-recommended 30-yr normals are no longer generally useful for the design, planning, and decision-making purposes for which they were intended. They not only have little relevance to the future climate, but are often ... -
Observational and Numerical Evidence of Depressed Convective Boundary Layer Heights near a Mountain Base
(American Meteorological Society, 2008)Recent field and numerical studies show evidence of the existence of a convective boundary layer height depression near a mountain base. This depression can have implications for air pollutant transport and concentrations ... -
